Poison de flèches de l'Indochine française

Through an examination of business relationships in the textile industry of Surat, a city in western India, this article evaluates different theories about the importance of social trust in economic development. The case study of Surat raises questions about models that posit a necessary expansion of broad civic ties or legal‐bureaucratic structures at the expense of close personal ties as a basis for industrial development. Surat's business people rely most strongly upon relationships to particular kins‐people, caste‐mates, and co‐religionists rather than broader civic bonds, formal legal controls, or bureaucratic systems as foundations for business trust. Although the expansion of the city's textile industry has created a greater need among the local population for impersonal, universalizing types of social trust, this article argues that these forms, show little sign of replacing personalized trust as the primary basis for local economic activity.     

Redefining Industrial Symbiosis

The most commonly cited definition of industrial symbiosis (IS), by Chertow (2000) , has served well to foster discussion and research for more than a decade. The definition reflected the state of research and practice at the time; as both have advanced, some terms have been interpreted in substantially different ways. In this article we analyze those generally used terms for their connection to the ecological metaphor that is the root of industrial ecology, and their varied interpretations in IS research and practice over time. We then propose an updated definition intended to communicate the essence of IS as a tool for innovative green growth: IS engages diverse organizations in a network to foster eco‐innovation and long‐term culture change. Creating and sharing knowledge through the network yields mutually profitable transactions for novel sourcing of required inputs and value‐added destinations for non‐product outputs, as well as improved business and technical processes. We posit that, although geographic proximity is often associated with IS, it is neither necessary nor sufficient—nor is a singular focus on physical resource exchange.     

Scaling‐Up of Industrial Symbiosis in the Korean National Eco‐Industrial Park Program: Examining Its Evolution over the 10 Years between 2005–2014

In 2005, South Korea initiated the 15‐year National Eco‐Industrial Park Development Program in three stages to gradually transform aged industrial complexes into eco‐industrial parks (EIPs) by promoting industrial symbiosis (IS). Building upon the pilot experiences from the first 5 years, the second phase of the program focused on the scaling‐up of IS at a broader regional level. Key scaling‐up strategies included the expansion of target areas by connecting multiple industrial complexes, the standardization of processes and dissemination of learning, and the development of large‐scale projects that could contribute to the regional development. In this study, we examined the evolution of IS over the last 10 years between 2005 and 2014, primarily to understand the characteristics and impact of these scaling‐up strategies. Our findings showed that the scale of IS in the second phase had increased in various aspects in comparison to that in the first phase. The number of operating projects had increased from 52 to 159, the number of participating firms increased from 90 to 596, and the average distance of IS increased from 40 to 48 kilometers. The size of economic and environmental benefits also increased along with an increase in the private investment and government research funding. We further analyzed the role of the regional EIP centers as facilitators, how their activities influenced the scaling‐up of IS, and discussed the characteristics of the Korea's approach to IS.     

Explaining Industrial Symbiosis Emergence,Development, and Disruption: A Multilevel Analytical Framework

Industrial symbiosis (IS) is the process by which by‐products are revalorized and exchanged among distinct business entities. The literature suggests that IS can bring financial, social, and environmental benefits to firms and society. Analytical tools have been developed for uncovering IS arrangements and guidelines suggested for designing IS arrangements where they do not yet exist. Despite these suggested benefits and in spite of these tools, few planned IS arrangements have successfully materialized, with notable exceptions in East Asia. Understanding why IS networks emerge and expand or falter requires both macro‐ and micro‐level analysis. Some explanatory factors have been extensively covered in the IS literature, such as the important role of coordinating organizations. But the analysis of enterprise‐level actions and strategies as well as the conditions in the external environment that act on the enterprises and the network are not as well examined. The article outlines an analytical framework that draws upon insights from research on cleaner production, corporate social responsibility, diffusion of innovation, and the role of the state in development. The framework is consistent with the view that the evolution of IS networks is characterized by “equifinality.” Different networks may achieve IS as a result of quite different combinations of factors. No general theory of IS success or decline is offered because no such theory can be expected. IS emergence, development, and disruption is approached as a problem of sociohistorical analysis. For such phenomena, analytical frameworks provide a common explanatory starting point, but no predictive power.     

Understanding the Organization of Industrial Ecosystems

Industrial symbiosis (IS) has been used to describe the physical exchange and shared management of input and output materials by geographically proximate firms. Firms that engage in IS are said to belong to an industrial ecosystem. Symbiosis has been found to be motivated by economic considerations, such as lowering costs for waste disposal, as well as by environmental ones, such as accessing limited water supplies. Communication and trust among managers are thought to play important roles in exchanges; however, empirical studies have not been previously conducted. This study used social network analysis (SNA) to identify the prevalence of industrial symbiosis linkages in Barceloneta, Puerto Rico. The study quantified patterns in various relationships among firms and managers, including formal relations through supply chains, and informal ones through interpersonal interactions. SNA and statistical methods were used to explore how these ties correlate with observed industrial symbiosis activities. IS linkages were found to be less prevalent than product sales among firms and were concentrated among pharmaceutical firms at the core of the regional network. Trust among managers and position in the social hierarchy were found to be correlated with IS but not supply chain links. SNA was useful for examining the organization of different relationships in the industrial ecosystem, but contextual information is still needed to add meaning to its findings.     

Barriers to Industrial Symbiosis: Insights from the Use of a Maturity Grid

The concept of industrial symbiosis (IS) over the last 20 years has become a well‐recognized approach for environmental improvements at the regional level. Many technical solutions for waste and by‐product material, water, and energy reuse between neighboring industries (so‐called synergies) have been discovered and applied in the IS examples from all over the world. However, the potential for uptake of new synergies in the regions is often limited by a range of nontechnical barriers. These barriers include environmental regulation, lack of cooperation and trust between industries in the area, economic barriers, and lack of information sharing. Although several approaches to help identify and overcome some of the nontechnical barriers were examined, no methodology was found that systematically assessed and tracked the barriers to guide the progress of IS development. This article presents a new tool—IS maturity grid—to tackle this issue in the regional IS studies. The tool helps monitor and assess the level of regional industrial collaboration and also indicates a potential path for further improvements and development in an industrial region, depending on where that region currently lies in the grid. The application of the developed tool to the Gladstone industrial region of Queensland, Australia, is presented in the article. It showed that Gladstone is at the third (active) stage of five stages of maturity, with cooperation and trust among industries the strongest characteristic and information barriers the characteristic for greatest improvement.

Regional Patterns in Global Resource Extraction

This article presents an account of global resource extraction for the year 1999 by material groups, world regions, and development status. The account is based on materials flow analysis methodology and provides benchmark information for political strategies toward sustainable resource management. It shows that currently around 50 thousand megatons of resources are extracted yearly on a global scale, which results in a yearly global average resource use of around 8 tonnes per capita. Assuming further growth in world regions not yet close to the levels of resource use in the industrial cores—such as India or China—numbers could easily double once these parts of the world come to fully incorporate the industrial mode of production and consumption. This article contributes to information on resource use indicators, complementing and enriching information from economic accounting in order to facilitate political measures toward a sustainable use of resources.     

Assessing the “Short Mental Distance” in Eco‐Industrial Networks

Like many economic exchanges, industrial symbiosis (IS) is thought to be influenced by social relationships and shared norms among actors in a network. While many implicit references to social characteristics exist throughout the literature, there have been few explicit attempts to operationalize and measure the concepts. The “short mental distance,”“trust,”“openness,” and “communication” recorded among managers in Kalundborg, Denmark, set a precedent for examining and encouraging social interactions among key personnel in the dozens of eco‐industrial networks around the world. In this article we explore the relationships among various aspects of social embeddedness, social capital, and IS. We develop a conceptual framework and an approach using quantitative and qualitative methods to identify and measure these social characteristics, including social network structure, communication, and similarities in norms and conceptions of waste, and apply them in an industrial network in Nanjangud, South India. The findings suggest that there is a fairly high level of shared norms about dealing with waste—the “short mental distance”—in this network, but by‐product transactions are only weakly correlated with the structure and content of communication among managers. Replication of this approach can increase the understanding and comparability of the role of social characteristics in eco‐industrial activities around the world.     

Industrial symbiosis in the forestry sector: A case study in southern Brazil

Industrial symbiosis (IS) is an important concept in the field of industrial ecology that has disseminated worldwide as a practice to decrease the ecological impact of industrial processes through the exchange of by‐products and waste between units in a system. The forestry industry is the main economic activity in the region of Lages in southern Brazil. IS relationships have expanded with the use of waste material from wood processing and strengthened cooperation between companies in different sectors. The aims of this article were to: a) quantify the level of IS in the system, b) identify the benefits of IS for participants, and c) explain why the network further developed IS to the formation of an industrial ecosystem. A questionnaire was administered during visits to 24 forestry companies in order to analyze their products and processes, commercial relations, positive impacts, and local insertion. The industrial symbiosis indicator (ISI) was determined using waste stream data from the system to represent the level of symbiosis among the companies in this region. The results show that the companies participate in a symbiotic network, mainly involving the exchange of chips, bark, sawdust and shavings. In most cases, these exchanges occur between nearby companies, constituting an extensive industrial ecosystem.

Industrial Symbiosis Dynamics and the Problem of Equivalence: Proposal for a Comparative Framework

Industrial symbiosis (IS), one of the founding notions within the field of industrial ecology, has diffused throughout significant parts of the world as a practice that can reduce the ecological impact of the industrial processes of groups of firms. In this article, we propose a fresh look at this research topic, building on the considerable advances that have been made in the last 15 years in understanding how IS comes about. We propose a conceptual and theoretical framework for taking on the challenge of comparative analysis at a global level. This requires developing an approach to address a solution to the problem of equivalence: the difficulty of comparing instances of IS across different institutional contexts. The proposed framework emphasizes IS as a process and attempts to address the obstacles to comparative study by (1) identifying terminology to examine IS variants, (2) providing a typology of IS dynamics, and (3) formulating key research questions to illuminate a way forward. In developing our argument, we build on the collective experiences of collaborative research efforts in North America, Europe, and Asia as evidenced in recent overviews of the literature.     

Evaluating the environmental performance of producing soil and surfaces through industrial symbiosis

Industrial symbiosis (IS), where different entities collaborate in the management of energy, utilities, materials, or services, has been identified as an approach to improve resource efficiency and circularity in industry. This article assesses the environmental performance of an IS network with firms involved in waste management, soil, surfaces, paper, lumber, and energy. The aim is to highlight the environmental performance of an IS network and pay particular attention to the improved performance for products in the IS network. Life cycle assessment is used to compare the current IS network with a reference scenario and a potential future development. The results suggest that there are significant benefits from the IS network. Large reductions in greenhouse gas (GHG) emissions and abiotic resource depletion were identified. Furthermore, large reductions in local impacts, namely eutrophication and acidification impacts are illustrated. It was shown that all firms in the network benefit from the synergies involved, with a large share of the benefits stemming from the facilitated exchanges with the waste management company. The replacement of conventional products and energy streams with bio‐based counterparts from within the network is of significant importance. Finally, the results point to the importance of the facilitation of by‐product synergies, and the significant value this creates in the region, with large potential to improve the environmental performance of firms and their products.     

The development of a frame model for management strategies selection using fuzzy proximity

This research is to discuss management strategies selection and enterprise life cycle periods referencing fuzzy proximity from fuzzy set theory and based on the current development situation of enterprises in China. First, this paper measures the degree of proximity for eight kinds of management strategies and different enterprise life-cycle periods (the pioneering period, growth period, maturity period and recession period) using a fuzzy proximity vector. The eight management strategies include management idea innovation, management organization innovation, management method innovation, management culture innovation, management institution innovation, market innovation, business model innovation and performance management innovation. Second, this paper analyzes management innovation strategies in different enterprise life cycle periods, and verifies the consequences using an example of the developmental history of one engine manufacturing enterprise since 1997. Several conclusions can be drawn from this research: (1) The frame model of management innovation strategies in the enterprise’s life cycle is both reasonable and convincing as a reference for management innovation strategies selection when enterprises are developing. (2) The fuzzy proximity method can be applied to research where a management innovation strategy during a particular life cycle needs to be selected. Therefore, this research extends the application and scope of the fuzzy proximity method.     

Learning before Doing

Over the past decade, advances in computing, combined with new techniques for virtual prototyping and simulation, have altered our approach to the areas of training, design, and product and process development. Taken collectively these capabilities represent one of the most significant changes in the production paradigm since the beginning of mass production and one with important implications for the environment. These advances need to be viewed as more than just a new set of tools in the industrial ecology tool box They provide the basis for a fundamental shift in how we learn and solve environmental problems-an opportunity to move from learning too late to learning before doing. Industrial ecology can embrace and articulate this new framework for learning and apply it broadly to the challenge of facilitating social and technological change and innovation in an increasingly complex world.     

Fighting pathophobia: how to construct constructive public engagement with biocontrol for nature without augmenting public fears

Social networks of stakeholders are necessary to foster public support for classical biological control for nature. Drawing from recent scholarship in policy-relevant social science fields, this article describes two key concepts that can improve science communication strategies to support invasive species management and biocontrol: lay public risk perception, and public engagement with science. This article then recommends a fundamental communication strategy: construct public trust in invasive species control efforts using public engagement processes that link trustworthy messengers and appropriate messages with the public. It draws examples from biocontrol projects that used pathogens as the natural enemy of choice, but more broadly seeks to inform efforts to engage the public about the use of classical biocontrol agents in nature conservation efforts.     

Locational Determinants of Emissions from Pollution-Intensive Firms in Urban Areas

Industrial pollution has remained as one of the most daunting challenges for many regions around the world. Characterizing the determinants of industrial pollution should provide important management implications. Unfortunately, due to the absence of high-quality data, rather few studies have systematically examined the locational determinants using a geographical approach. This paper aimed to fill the gap by accessing the pollution source census dataset, which recorded the quantity of discharged wastes (waste water and solid waste) from 717 pollution-intensive firms within Huzhou City, China. Spatial exploratory analysis was applied to analyze the spatial dependency and local clusters of waste emissions. Results demonstrated that waste emissions presented significantly positive autocorrelation in space. The high-high hotspots generally concentrated towards the city boundary, while the low-low clusters approached the Taihu Lake. Their locational determinants were identified by spatial regression. In particular, firms near the city boundary and county road were prone to discharge more wastes. Lower waste emissions were more likely to be observed from firms with high proximity to freight transfer stations or the Taihu Lake. Dense populous districts saw more likelihood of solid waste emissions. Firms in the neighborhood of rivers exhibited higher waste water emissions. Besides, the control variables (firm size, ownership, operation time and industrial type) also exerted significant influence. The present methodology can be applicable to other areas, and further inform the industrial pollution control practices. Our study advanced the knowledge of determinants of emissions from pollution-intensive firms in urban areas.     

Using an Industrial Waste Account to Facilitate National Level Industrial Symbioses by Uncovering the Waste Exchange Potential

The identification of potential by‐product exchanges is important for fostering industrial symbiosis. To discover these potential exchanges, this article extends the analysis of local industrial symbiosis to a national scale. A waste input‐output table, which is a material flow accounting tool, was compiled and used as a database to examine the existing exchanges of by‐products. The supplies and demands of industrial wastes or by‐products were compared to highlight their potential use for promoting higher exchange flows. The analysis of the linkages indicated that the majority of each of the by‐products were reused by the few industries that had the technology and operational capacity for reuse. This finding is useful for determining which industries are good candidates for promoting further industrial symbiosis (IS). Based on a nation‐wide analysis that considered the industrial characteristics of Taiwan comprehensively, 23 types of major by‐products with greater reuse flows and 216 potential exchange patterns were identified between the industries. In addition, three types of eco‐industrial networks were characterized as follows according to their dominant types: (1) fossil fuel, metal, and mineral‐dominated; (2) agricultural and synthetic material‐dominated; and (3) information and communications technology (ICT) and chemical industry‐dominated eco‐industrial networks. This analysis highlights the resource exchange potentials and provides information to new firms for networking with existing businesses.
